Is the refusal of a girl's parents to marry her off, despite her being competent, under the pretext of completing her studies and their condition that the suitor be a doctor or an engineer, while the girl agrees to another suitor, considered an 'adl' (unjust prevention of marriage) that nullifies their guardianship, and what can be done in this situation in a country where there are no Sharia courts or Sharia judges?

If the father has no legitimate Shar'i reason to reject a suitor, he has acted wrongly and is thus preventing her marriage (عاضل), and his guardianship falls. Guardianship transfers to the Sultan if all guardians refuse to marry her off, for the Sultan is the guardian of one who has no guardian. In countries where there are Sharia courts (called family courts), the Shar'i judge acts in place of the Sultan. A man is not permitted to marry a woman except with the permission of her guardian or by the ruling of the Shar'i judge. It is advisable to be patient and try to convince the family, but if marriage is not facilitated, then the relationship with the girl must be severed because she is a stranger (أجنبية).
